Taking your post at face value;

"Just walk away", what is wrong with you? You entered a business transaction, she did not deliver. Send her a business professional email requesting an explanation or refund. Give it a week or so and if she doesn't rectify the situation THEN post here. No whining, crying, flaming, emotional outbursts, doxxing, simply name the individual that stole your money.

I've had more than my share of problems with the "pros", I've even had to walk away from my deposit. But never had one steal from me, if I had it would certainly be made known as a courtesy to anyone else considering said provider.
